Is there a way to show a message "Please click on a match to get started" when no match link has been clicked? For example, when the iframe does not have an src attribute. My backend is built on Django. Below is the HTML code snippet:
</form><br>
{% for match in all_matches %}
<li style="list-style:none; text-align: center"><a style="padding: 6px 8px 6px 16px;text-decoration: none;font-size: 18px;color: #ffffff;display: block;" href="{{match.url}}" target="iframe1">{{match.name}}</a></li>
<hr class="new1">
{% endfor %}
</div>
<div class="col-sm-9 col-xs-9 col-md-9 col-lg-9" id="frameContainer">
<iframe name="iframe1" id="fr" style="display: block;" width=100% height=100% frameborder="0" allowFullScreen="true"></iframe>
</div>
